- Background: Long-term survival for selected patients with peritoneal metastases (PM) from colorectal cancer (CRC) is possible when treated with cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). The objective of this study was to compare three different oxaliplatin-based (OX)-HIPEC regimens. Primary end-point was disease-free survival (DFS), and secondary endpoints, morbidity and overall survival (OS).Methods: This is a retrospective study of all patients with colorectal PM treated with CRS and HIPEC between 2004 and 2015 from the prospectively maintained Uppsala HIPEC database. One hundred and thirty-three patients were identified. Three HIPEC regimens were included: OX-HIPEC, OX-HIPEC + post-operative intraperitoneal chemotherapy (EPIC) with 5-fluorouracil (5-FU), and oxaliplatin-irinotecan-based (OXIRI)-HIPEC. Multivariable Cox regression for DFS was performed.Results: Sixty-one patients received OX-HIPEC, 24 patients received OX-HIPEC + 5-FU EPIC, and 48 patients received OXIRI-HIPEC. The DFS for the OX-HIPEC group was 10.5 months, OX-HIPEC + EPIC 11.9 months, and OXIRI-HIPEC 13.4 months (OX-HIPEC vs. OXIRI HIPEC, P=0.049). The morbidity and OS did not differ between the groups. In the multivariable analysis, low peritoneal cancer index (PCI), absence of liver metastases, low completeness of cytoreduction (CC) score, and multiple drug (EPIC or OXIRI) HIPEC regimen were independent prognostic factors for DFS.Conclusions: This study showed improved DFS with an intensification of HIPEC by adding irinotecan or EPIC compared to oxaliplatin alone without an increase in morbidity or mortality.

- Introduction: Early post-operative intraperitoneal chemotherapy (EPIC) can be used after cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) in patients with resectable peritoneal metastases (PM). Whether EPIC adds any benefit is debatable.Methods: We performed a retrospective case-control analysis of patients with PM of appendiceal origin treated by CRS + HIPEC +/- EPIC at Uppsala University Hospital between 2004 and 2012. The 206 patients were divided into two groups depending on if they received EPIC or not. The two groups were propensity-matched with a 1:1 ratio. The patients in the EPIC group were mostly operated in the first three years of the unit's experience.Results: After matching, 76 patients were left in each group. The groups were similar, except for the proportion of histological subtypes (p = 0.021) and chemotherapy agents used for HIPEC (0.017). Survival outcomes were stratified by histology. The patients who received EPIC had a longer hospital and ICU length of stay (15.71 vs 14.28 days, p = 0.049), (1.45 vs 1.05 days, p = 0.002), respectively. Post-operative complications were similar in both groups. Overall Survival (OS) and recurrence-free survival (RFS) did not differ for the patients with low-grade histology. The patients with high-grade tumors who received EPIC had a significantly worse OS (p = 0.0088) while having the same RFS as the patients who did not receive EPIC.Conclusion: Our results suggest there is no benefit of EPIC in patients with advanced appendiceal tumors while increasing hospital and ICU length of stays. A suboptimal group matching might influence our results. (C) 2020 Elsevier Ltd, BASO similar to The Association for Cancer Surgery, and the European Society of Surgical Oncology. All rights reserved.
